Study Notes
Optics and Lenses
- Thin lenses in optics primarily focus light to create precise images.
- A ray passing through the center of a lens passes through without bending.
- Light rays parallel to the principal axis of a converging lens converge at the focal point on the opposite side.
- An image projected onto a screen is a real image.
- Modern devices like hard drives utilize magnetism.
Energy Transformations
- Electric motors convert mechanical energy to electrical energy.
Transformers and Generators
- Natural sources like steam, wind, and hydropower are common generator fuel sources.
- Transformers adjust electrical voltage through primary and secondary coils.
Magnetic Poles
- Unlike magnetic poles repel each other, while like poles attract.
Hormone Regulation
- In males, inhibin regulates FSH levels.
- GnRH from the hypothalamus triggers FSH and LH release.
- LH's primary role in males is to stimulate testosterone synthesis.
Menstrual Cycle
- The proliferative phase involves uterine lining thickening.
- The menstrual phase involves the shedding of the uterine lining.
- The corpus luteum is active during the secretory phase.
Other Questions
- hCG maintains the corpus luteum during pregnancy.
- Light rays passing through the focal point of a diverging lens exit parallel to the principal axis.
- Light rays converging form real images.
- Oxytocin is responsible for milk ejection. Estrogen influences uterine lining thickening.
Modern Devices
- Electronic devices such as fans and cameras are powered by electrical motors.
Androgens
- Testosterone is the primary androgen in males.
